PLOW.

'Application llled November 4, 1922. Serial No. 599,108.

To all 'whom it may concern: Be it known that I, LEE P. BIGGEns, acitizen of the United States, residing at Palmersville, in the county ofWeakley and State of Tennessee, have invented a new and useful Imrovement in Plows, of which the following 1s a specification.

My invention relates to a plow of the rotary type which may also be usedas a pulverizer by an interchange of the earthworking elements or tools,or by employing elements or tools of both types, may be used both toplow and harrow simultaneously.

One of the important features of the 1nvention relates to the manner inwhich the earth-working elements are disposed, whereby the rotation ofthe same, in add'- tion to working the earth, furnishes either a part orall of the force by which the implement may be propelled over thesurface of the ground.

A further object of the invention is .torso Figs. 7 and 8 are detailviews of different types of earth-working elements.

eferring now to the details of construction. The invention comprises arectangular frame having front and rear members l and 2, respectively,connected by side members 3 and 4, each of which is provided with aflange 5 at each end secured to the members l andg by bolts 6 or thelike. The frame members 1 and 2 are each made hollow and provided alongthe inner edge with slots 7 and 8, respectively, through which theshafts that carry the earth-working elements exas journal bearings forthe shafts 11. Bc-I constructv the implement that the vaious,j;/t\veenthese blocks 10 are arranged alterparts thereof may be easily assembledorI disassembled for the purpose of replacing worn or broken parts, orfor sharpening the earth-working elements. l

The invention consists further in the ar- 36 rangement of the shafts onwhich vthe earthworring elements are mounted so that they extend in thedirection of the line of draft, and also in the arrangementof thcearthworking elements on the shaft, so that part of them are engagedwith the ground while others are in the air, and the elements on eitherside of the machine are so balanced that there will be little tendencyto move sidewise.

The'invention will be better 4understood by the following description,taken in connection with the accompanying drawings, which illustrate onestructure by means of which the invention may be carried out.

In the drawings v Fig. lis a plan view of the invention.

Fig. 2 is a horizontal sectional view.

Fig. 3 is a rear elevation.

Fig. 4 is a side elevation.

Fig. 5 is a plan view of a ortion of the invention showing a modifieconstruction.

Fig. 6 is a detail sectional view showing the means for mounting theplow shafts.

nately the complementary spacing blocks 12, which may also be rovidedwith bearings 13 for receiving a ditional shafts, or in order to providefurther latitude in the relatiffrfe arrangements of the shafts. Theblocks 0 and 12 are secured at the ends of the members 1 and 2 by endblocks-14, which may be adjusted by means of screws 15` or the like.

The shafts 11 are preferably provided at their forward ends with ballraces 16 which take up the forward thrust exerted by the earth-workingelements 17 or 18 carried by the shafts.

It will be noted that the earth-working elements are disposed in planeswhich are inclined to the direction of the shafts on which they aremounted, -so that as the elements engage the ground, the will exert aforward thrust against the rame of the implement after the manner of aship propeller. The elements 17 have the same function as ordinary diskplows, but, as shown, are preferably made in the shape of sectors and sodisposed in relation to the circumference of the shafts that certain ofthe disks engage the ground while others are in the air, thusdistributing the load so as to obtain a Continous and substantiallyuniform action and thereby make it possible to operate the low with lesspower than would otherwise be necessary.

In order that the disks 17 may be removed I with the least possibletrouble, when it is necessary for t em to be sharpened, each disk ispreferably provided with a slotted hub, as shown at 19, whereby -thesame may be applied to the shaft and secured thereon by means ofclamping members 2O and 21,

l5 of the members 2O and 21 are to the axis of the shaft 1l, in order tofur- `nish the pro elling force. In actual practice, the pre erred anglehas been found to 20 be about 12 degrees from a perpendicular,

but this may be varied accordin to the s eed of revolution and the widtiof eut esired. The ulverizing elements 18 are formed each with a hub 24ada ted to re- 25 ceive the shaft, and a cap 25 whic i is securedthereto by means o f bolts 2G.

The' shafts 11 may be driven in any suitable manner. In Figs. 1 to 4, Ihave shown each shaft provided with a sprocket wheel 80 27, which isconnected, by a s rocket chain 28, to the drive shaft 29, that ismounted in bearin s at the upper ends of the standards an 31, risingfrom the main frame of the machine and from the motor support 32,

Il respectively. The shaft 29 is driven through bevel caring 33 or thelike from the motor 34 which, as will be understood, may be profvidedwith the usual clutch and gear shi t.

In Fig. 5, I have shown a modified driving gear in which the shafts 11are extended, as at 35, through the slot 9 at the forward side of theframe member l, and provided at their forward ends with a bevel earconnection 36 with a eountershaft 37 ournaled in bearings 38 at theforward si e of the frame. This countershaft 37 may be provided with asprocket wheel 39, that may be connected with the motor shaft, by theusual sprocket chain.

The frame of the machine is sup orted at the rear, the proper distance aove the ground, by means of wheels 40, each of which is carried by afork member 41, the

latter being adjustably connected by means of corrugations or teeth 42with an upstanding bracket 43, secured to the side of the frame. Themembers 41 and 43 are secured in their adjusted relation by means of abolt 44 which extends through the member 41 and through a slot 45 in thebracket 43.

The front or steering wheel 46 is secured at the lower end of a forkmember 47, which is rotatably mounted in a bearing 48, and held againstlongitudinal movement by a collar 49. The fork member 47 is provided atits upper end with a tiller arm 50. The bearing member 48 is formed in abracket 52, adjustably connected with a standard 51, in a manner similarto the rear wheel forks.

It is understood that the plow disks 17 will be set at such aninclination to the shafts 11 that, ordinarily, the machine will bepropelled over the ground by the forward thrust exerted by the disksupon rotation, and that the disks will, at the same time, plow theearth. In order, however, to use the machine under all conditions and inall kinds of ground, it may, in some instances,

be necessary to employ one or more draft animals or a tractor tosupplement the proelling force ofthe lows. In such cases, iowever, onlya smal additional force will need to be exerted by the draft animals.

As illustrated in Figs. 1 and 2, each of the shafts l1 may be providedwith both a plow disk 17 and a pulverizing tooth 18, so that one tripacross the ground will both plow and harrow it.

The essential features of the invention may also, with slightmodifications in the frame, be used in road grading. It will also. beobserved that an implement constructed according to my invention may becompletely disassembled in the least possible time by removing thescrews l5 and bolts 6 at one side of the frame.

While I have shown and described the specific construction of thoseforms of my invention which are at present preferred, it will beobserved that various modifications may be made therein within the scopeof what is claimed without departing from the spirit of the invention.

What is claimed is 1. In a wheeled low, a plurality of parallel shaftsdisposed? substantially 1n the line of travel, sector-shaped disk lowsri idly mounted on the shafts in planes ob ique to the axes of the resective shafts, a pulverizing tooth on eac to the direction of the shaft,and a motor to which the shafts are geared to rotate in unison, saidshafts being so disposed that certain of the disk sectors on each sideof the implement will engage the round simultaneously while others oneac side are above the ground, whereby the load is distributed so as toobtain a continuous and substantially uniform action.
